Who we are

It may have become a cliché, but Flagstone really did begin over coffee across a kitchen table. In the midst of a global financial crisis and falling interest rates, two friends had a vision to revolutionise the cash deposit and savings market.

Crammed into a basement with a team of four – plus a disobedient Labrador, Rocky, we set out on our mission to upset the status quo, and create a better way for people to get better returns on their investment, while protecting their cash.

As the UK’s leading cash deposit platform, our goal is simple: To be the trusted protector of the UK's cash deposits.

To date we have placed more than £13bn in client assets and today, our award-winning, innovative and secure platform provides access to hundreds of accounts – including exclusive and market-leading interest rates – from 60+ banking partners.

Our clients are individuals, business leaders, charities, entrepreneurs, and guardians of family wealth. By challenging the status quo, we empower our clients to not only protect their money, but to maximise its possibilities. We protect the art of the possible.
